Alienstock, the event jokingly conceived by college student Matty Roberts to storm Area 51 on September 20, is officially canceled. When more than 500,000 planned to attend and another 500,00 indicated they were interested in the Facebook event back in July, the U.S. Air Force took notice and issued a strongly worded statement that discouraged the plan.

 

But that hasn’t stopped an unknown number of people from planning to descend on rural Nevada this weekend, leading the FAA to shut down airspace above Area 51 as a precaution. This interest in the unknown isn’t new and to shed some light, BackStory is republishing our 2018 episode about UFOs in American History. In “Close Encounters,” Nathan, Brian and Ed discuss the things in the sky we struggle to explain – unidentified flying objects.
